That's really odd, you should see eth0 if it's still on the old device
names. And I thought everything had switched to the new device names,
so it should be enp4s0 or something like that.

You didn't do "modprobe rt2800pci"? I know people are in a big hurry
and don't read carefully, but that should've been the first thing you
tried. Mint should be good about finding hardware, but sometimes things
screw up. If the modprobe worked, immediately after running the
modprobe, you should see something like:
[34.5678] rt2800pci 0000:02:01.0: enabling device
[34.5678] rt2800pci 0000:02:01.0 wlp2s1 : renamed from wlan0
...in the output from dmesg.
Also, many wireless cards these days require firmware.[0] Did you
install that? That should've been done as part of the initial install,
but maybe it wasn't done for whatever reason. No idea what Mint does,
but the package should have "firmware" in its name. The Debian package
is called firmware-ralink so Mint's package will probably be named
something similar. You will have to tell Mint to allow non-Free
software to install that.

The only thing you should have to do to get almost any wireless card
working these days is install the firmware files and load the right
module. And then set it up with ESSID and password.
[0] Firmware these days is not GPL, so if you did something like "only
install GPL, Apache, MIT, etc licensed stuff" then you won't have the
firmware you need.
